These are Moonshine rat snakes. The original male was found in Horry County, SC by my friend Jim Godfrey. It is a tyrasinase positive albino (T albino). He also captured a female normal colored about 100 yds from where he found the Moonshine male. This is about as locale specific as it gets! And it is a locale specific morph to boot!! These come from the integrade region where black rat snakes and yellow rat snake range overlap producing the greenish rat snake. The name Moonshine rat snake was coined because the pattern on the original male's head reminded Jim of the craters you see when looking at the moon. The sire to my hatchlings was the original wild caught Moonshine male. These are the very first visual to visual breeding hatchlings. When they mature the take on a very bright yellow coloring that is much brighter than the yellow rat snakes.
